To all whom it ma concern:

Be it known t at we, ANDnnw L. W'nrs and FRANK N. WEIS, citizens of the United States, residing at Monroe, in the county of Monroe and State of Michigan, have invented certain new and useful Improvements in appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

Our invention relates to mechanism for performing one of the steps in the manufacture of boxes composed of paper, pastboard or the like. Assuming that the box is completed,.x cept that the several overlapping flaps or members which compose one end of the box remain to be pasted or glued together and that the opposite end of the box is closed but has a hole therethrough for the reception of a stopper; the present invention is designed to press together the pasted or glued meeting surfaces of the flaps or mem bers of the unfinished end and to hold them tightly pressed together for-a time until the adhesion between such surfaces shall be comlete. p To this end, our invention consists of the devices and arrangement of parts hereinafter specified, and shown and illustrated in the accompanying;1 drawings, in which-- Figure 1 is a OIIt-GlGViLtlOIl of our machine with certain portions omitted for the sake of clearness, as will hereinafter fully appear; Fig. 2, a top-plan view of the same with a portion of the top table broken away;

Fig. 3, a side-elevation of the step-by-step turning mechanism hereinafter referred to; Fig. 4, a top-plan view taken on line 44 Fig. 1; Fig. 5, a side-elevation, partly in section, of the sectional table or bed and the platen hereinafter referred to with the means 7 for actuating the same in operative position;

Fig. 6, an enlarged view, in detail, of the sectional folding table, hereinafter referred to, in position to receive the box to be fin ished, together with the support therefor, and the device for lifting the box at the completion of the operation, and Fig. 7 a topplan view of the same. a

Corresponding parts are. represented by like numerals throughout the drawings.

In the drawings, 1 is a pedestal. upon the top of which is rotatively mounted a circular frameconsisting of an upper ring 2 and a lower ring? These two rings are held in proper separated relation by bars 4 and have spo es and hubs and are supported upon the top of the pedestal and j ournaled upon shaft 5 which is supported in a socket in the top of the pedestal l, the shaft being held against rotation by a set-screw 6. Rigidly secured toand projecting upwardly from the ring 3 is a series of posts or standards 7, each having a central vertical slot in its top, as at P, (Figs. 5 and 6.)

88 are pairs of identical plates, each having a flat-surfaced member 8, rectangular in outline or otherwise,according tothe shape of the box to be operated upon, and each having a finger 8 formed integral therewith and projecting at a right angle to the member 8*. The two plates are each pivoted, as at- 8, at the meetin angle of the parts 8 8 in the upper end of the slots 7 of the bars 7 The arrangement of these pairs of plates and their pivots is such that when the members 8 are thrown into upright-position the flat surfaces of the two members meet and exactly coincide, and such that when the parts 8 areswung outwardly away from each other withtheir flat surfaces in the same horizontal plane the two arms 8 will meet, as shownin Fig. 5 and in dotted lines in Fig. 6, and will' 'hold the 5 parts 8 so that their flat surfaces will now present a horizontal bed ,orltablei. The slot 7 permits this tiltin of thegpairs of plates upon their pivots. s or pieces 8 (see Fig; 7.) are interposed between the jaws of the slots? and the sides of the tiltingmembers 8%81t'o revent the parts 8 from-accidentally fal in apart. Each of the upright bars"? is provi ed near its lower end with a plate 9 which is movable vertically upon the part 7. The normal height of these plates upon the. standards 7 may be regulated to conform to the size of the box to be operated upon, by means of siilpportgng 'pins 9 inserted in holes 9,

ig. 5. If the two members 8% be brought together, as indicated in Figs. 6-7, and if the 1 opening in box A, indicated in dotted lines light. friction-springs these flaps be pressed with sufiicient force and held closely together for a suflicient time the work of closing and securing the uncompleted end of the box will be finished. This part of the operation is accomplished by means of the mechanism now to be described.

Upon the ring 2, at intervals corresponding with the standards 7, are pairs of upright lugs 10. Each of these pairs of lugs pivotally supports, as at 11,a frame 12 (see Fig. 5 resembling somewhat in side-elevation a ell-crank lever. The arms 12 of this frame carry a roller 13 and the arms 12 of the frame carry a roller 14. Passing through the arms 12 are pins 15, headed at their upper ends and rigidly connected. at their lower ends with a platen 16 coinciding in outline with the flat surface of the table 8 8-. A stiff spring 17 is interposed between the platen and the arms 12.

18 is a flat ring or wheel rigidly secured to and concentric with the upper end of the fixed shaft 5. This ring is not continuous, but has, at the front part of the machine, a gap. (See Fig. 2.) In the gap is secured a curved bar 19, which is formed as a cam 20 upon which the rollers 13-14 successively ride as the frame 2-8 is rotated. The-cam 20 and rollers 14 serve to successively throw the arms 12*, the rollers 13 and the platens 16 into upright position, as indicated by the dotted lines in Fig. 5. At this point there is a pause in the rotation of the frame 2-3 to permit the box-blank under treatment to be slipped into place over the standard 7.

As the frame 23 starts forward on its rotary course, the cam is of such contour that it releases the roller 14 and at the same time swings the roller 13 down, at 18 so that it passes under and rides upon the lower side of the ring 18. This contact, through spring 17 presses the platen 16 downwardly with a heavy but yielding pressure, thus compressing the flaps of the box closely between the top of the table 8" and the bottom of the platen. This pressure is continued during the greater part of the revo lution of the frame 2-3 and during its several pauses until the roller 13 emerges from beneath the ring 18 at 18 where the roller 13 and the platens are released to be by the cam 20 again swung upwardly, as indicated by the dotted lines in Fig. 5, as above described. In the accompanying drawings there are shown,--for illustration,-twelve holders and presser-mechanisms all like the one hereinbefore described, as will be readily understood, although the parts are not all repeated in the drawings. step rotation of the frame 3 and its appendages may be performed by suitable power driven mechanism, but in the present instance is effected,-for illustration,-by means of a treadle 21 pivoted upon the base, as at 22, and pivotally connected by rod 23 with 'one arm of a bell-crank lever 24, the other end of this lever being loosely connected with a bar 25 sliding in a housing 26 and carrying a pawl 27 which engages the teeth The step-byof a ratchet-Wheel 28 fastened concentrically to the underside of frame 23. The pawl is held against the ratchet by means of the pressure of a fiat spring 29, one end of which is rigidly secured to the sliding bar 25. The treadle is held normally elevated by spring 21 but when the treadle is depressed by the foot of the operator, the pawl,-through the sliding bar and bellcrank lever,moves the ratchet-wheel and the frame 2-3 to which it is secured a single step which, in the present instance, is one twelfth of a revolution. The frame now pauses and the platen immediately in front of the operator at the same time is, by the .cam 20, thrown upwardly and out of the way, as illustrated in dotted lines in Fig. 5, so that the con'ipleted box may be removed and replaced by an uncompletcd one.

To facilitate the removal of the box after it has emerged from beneath the ring 18 at 1S we provide a radial arm 30 rigidly connectcd, as at 31, to the pedestal 1 and carrying at its outer end a vertically adjustable rod 32 which has at its top a wedge-like cam 33 which lies in the path of the beveled underside of the plates 9. As the boxes successively emerge from beneath the segmental ring 18 and as the platen 16 is lifted out of the way, the plate 9 rides upwardly upon the inclined surface of the member 33 and lifts the box some distance so that it may now be readily removed from the machine, by a reversal of the above described movement of the parts 8 Above and supported by the ring 18 is a flat circular table-top 34 which protects the mechanism located below the table and serves as a convenient resting place for boxes as they are supplied to the operator and as they are removed from the machine.

Having described our invention, what we claim and desire to secure by Letters Patent is,

1. In a device of the described character, a frame, a standard upon the frame, a sectioual table pivoted upon the standard, the sections of such table being pivoted to be throwninto parallel relation or into the same plane, combined with a platen co-act- 'ing with said table.
